Are there degrees of sin?
Q. I do not believe God considers all sin to be the same. I base this on the words of Jesus. He was responding to Pilate who had said, “Don’t you realize I have power either to free you or to crucify you?” In John 19:11, “Jesus answered, “You would have no power over me if it were not given to you from above. Therefore the one who handed me over to you is guilty of a greater sin.” I realize that any sin, no matter the magnitude by our earthly standards, separates us from God. We all need salvation through Jesus. Even so, don’t you think that Jesus’ words in John 19:11 means that God does in fact see sin in degrees?
A. Pilate was an unbeliever who didn’t have any idea who Jesus was. He was acting in ignorance. But at some level the priests who handed Him over had to know they were putting the Son of God to death.
